Dear Keith, good question. As a former budget officer in the Department of Defense (DoD), let me point out that, unless things have changed, the retirement and health plans of the DoD are within the existing budget. Each year, medical plans and a large part of the retirement programs have to compete with other items within the DoD budget, although, of course, they are fixed items and obligations which were part of the package when people signed up to put their lives on the line (and if we tell people the government is reneging on those promises, can the military or police likewise tell the government to "stuff it" when they are sent to a dangerous location?).
Unlike other "quasi-debt" and discretionary spending (like the "bailout" plan), retiree expenses can be planned for and budgeted for with some ease so their impact on inflation should be quite low. Items such as veteran's care depends on how often we ask our military to be exposed to difficult situations like war. Hope this helps.

I was amazed to learn the Federal Government portion is so small compared to the Domestic portion of debt. Would like to understand more completely.
